To shut off the water to your house, find the valve that controls the flow of water into your house, and then turn that valve clockwise until it stops moving. Contact a plumber immediately if you are turning the water off for an emergency leak or pipe burst.Continue Reading
Search around the house for the valve if you do not know where it is. Look near the perimeter of the house, generally on the same side of the house as the main water valve that the city controls. Look in the landscaping if this is on the front of the house, as you may find a plastic housing that has the valve inside. Consult the inspection report for your home if you cannot find it.
Move to the water meter if you cannot find the shut-off valve nearest the house. Open the lid to the water meter, and move away any sand or dirt with a small trowel or your hand. Set this nearby, as you need to put it back in if you live in a place that experiences freezing temperatures in the winter; this sediment is part of the protection against a hard freeze.
Grasp the valve, and turn it clockwise until it stops moving. Look for a knob or a nut on the house side of the city water meter. Do not turn off the city valve; use the secondary one instead, as this is designed for owner use. Use a combination wrench to turn the nut clockwise until it stops moving, or turn the knob by hand.
